I will concede that economic and social inequality and oppression is supported by the state monopoly on violence.
State and capital is almost inseparable in most modern economies. It does not follow, however that this inequality and oppression would cease to exist if the state ceases to exist.
After all, this oppression is not dependent on the state,it uses the state conveniently, but it also uses private security companies and even private armed forces, for instance to chase peasants away from their land,when the state has sold the land that they have used for generations.
This happens especially in countries with a lot of corruption, and lack of state regulation.
Remember that politicians and bussinessmen are often the same people. Corruption abound.
This corruption and abuse of power has to be dealt with,and people will never want to get rid of the state, when they have no faith in capitalists and market forces to bring about justice.
Rather most people,like me, would expect the law of the jungle to take over.
